Heavenly Mechanism Forges Mortal Bones

In this world, all cultivators rely on the dantian as their root and spiritual energy as their foundation, gathering qi to open meridians and ascend step by step. But Lin Yan alone was born with a sealed dantian and turbid qi locked in his meridians, deemed a cripple for life, with no hope for martial arts. At fifteen, he fell off a cliff into a desperate situation, and on the brink of death, he awakened the Heavenly Mechanism Eye, able to see through vitality and medicinal properties, and perceive blockages in the flesh. Just then, a veteran of a hundred battles entrusted him with his final teachings, passing down the only forbidden reverse-cultivation technique in the world—the Iron Bone True Art. No dantian cultivation, no spiritual energy absorption, no heavenly secrets—only flesh and blood to temper bones and sinews, and bitter toil to forge a mortal body. Seven days of medicinal baths to cleanse the fetus, a hundred days of sinking into mountains to steady the stance, a thousand days of hammering bones to vibrate the meridians. While others refine qi and cultivate mystery, he refines skin, sinews, bones, and marrow; while others circulate qi through the heavens, he uniquely opens vibrating meridians, using primal blood as the source and a hundred bones as the path; while others rely on spiritual energy to dominate, he uses transmitted warmth, sound, and vibration to shatter bones with a single fist and collapse enemies with a single tremor. Mortal bones have no fate, but bitter toil can reverse it. From a crippled prisoner at the bottom of a cliff to treading the snows of the northern frontier and sweeping away the shackles of the jianghu, Lin Yan, with a mortal body despised by all, stubbornly forges a path of defiance—Heavenly Mechanism forging bones, mortal flesh surpassing immortals! — Description from novelcodex.org
